When organizing the resources across multiple teams, you want to make a suitable isolation plan to avoid the resource competition between different teams and applications and provide high-quality messaging service. In this case, you need to take resource isolation into consideration and weigh your intended actions against expected and unexpected consequences.</p>
<p>To enforce resource isolation, you can use the Pulsar isolation policy, which allows you to allocate resources (<strong>broker</strong> and <strong>bookie</strong>) for the namespace.</p>

<p>In Pulsar, when namespaces (more specifically, namespace bundles) are assigned dynamically to brokers, the namespace isolation policy limits the set of brokers that can be used for assignment. Before topics are assigned to brokers, you can set the namespace isolation policy with a primary or a secondary regex to select desired brokers.</p>
<p>You can set a namespace isolation policy for a cluster using one of the following methods.</p>

<p>A namespace can be isolated into user-defined groups of bookies, which guarantees all the data that belongs to the namespace is stored in desired bookies. The bookie affinity group uses the BookKeeper <a href="https://bookkeeper.apache.org/docs/latest/api/javadoc/org/apache/bookkeeper/client/EnsemblePlacementPolicy.html">rack-aware placement policy</a> and it is a way to feed rack information which is stored as JSON format in znode.</p>
<p>You can set a bookie affinity group using one of the following methods.</p>
